Drivers Door Window/Locks aren't working

I have a 2003 Grand Cherokee Laredo w/ 115,000 miles. My drivers side door started doing weird things about 2 weeks ago. The controls only worked when the door was closed. If you tried to hit the door locks when the door was open, nothing worked. Yesterday, I closed the door and now nothing works. The windows don't work, including the controls on the other doors, it won't lock automatically when you start driving either. So, I can't roll down any windows and neither can any of my passengers. Could this be some sort of switch in the door the controls everything?? Please help!
